Nature is the inspiration for solving several critical challenges currently facing the aircraft design industry. Several ongoing research projects include but are not limited to using structures and biomimetic adaptations to improve the aerodynamic characteristics of aircraft. One of these challenges is the drag force produced by an air vehicle's vertical stabilizer. Vertical stabilizer is a critical air-vehicle part for stability, but it also contributes to significant increase in drag, especially for commercial air vehicles within transonic speed. Investigating the total mission of an aircraft, the vertical stabilizer will be utilized during takeoff and landing and will also play significant role to stabilize the aircraft during One Engine Inoperative (OEI) conditions. While the vertical stabilizer is critical for aircraft, more than 90% of the aircraft mission will be flying under cruise condition at high altitudes where the use of vertical stabilizer is minimum. This research seeks to investigate potential nature inspired techniques to decrease the drag force using a variation design based on biomimicry by applying the hydrodynamic features of the sailfish (Istiophorus platypterus) to the vertical stabilizer for potential fuel saving and hence economic and environmental benefits. This study used computational Fluid dynamics methodology to morph a two-dimensional airfoil's leading edge incorporating sailfish geometrical features. The main objective of this study is to generate a more streamlined shape to reduce the pressure drag, which contributes about 10% of drag generated by the streamlined airfoil shape. The study found that the drag force will increase as the length to the sharp edge increases and decrease as sharp edge decreases until it reaches the same value as the original airfoil shape. The studies were performed using NACA 0012 airfoil as it is a symmetric airfoil predominantly used for vertical stabilizers. Seeking to reduce the pressure drag by a smoother, streamlined shape also caused increased skin friction drag value. Skin-Friction drag coefficient is considered the primary source of drag value in streamlined shapes at the laminar flow, while form drag is the primary source of drag value at turbulent flow. further study is needed to extend the study by performing the analysis using different shapes to the vertical stabilizer to investigate reduction in the drag generated and perform a comparative analysis using both experimental and three-dimensional simulations.
